Well, speaking from a relatively new player's perspective I think that FF14 is a good game, but at the same time I already have cancelled subscription so I can play another game after it ends. The subscription I have is the month I got for free plus two weeks for being invited to the game I think. I'm not quitting though, I'm just going to mix it in with other games. Anyway I think the problem is both FF14 and myself.
My problem is that I've played so many other MMO's that it just feels like I'm doing the same thing again at FF14 that I simply do not feel dazzled even as a new player. If it was my first, second or even third MMO I would have loved it, but no not this isn't my first rodeo, far from it.
FF14's problem is that its content is more driven by quantity than quality. ARR content feels more like a bland tutorial than anything else. Quests in general, other than the story, is more or less overly simplified. Well, I think that the content USED to be of both quantity and quality but it has aged. I don't think it's devs' fault though. MMO as a genre has aged itself and started hitting creativity walls of late. Sure there are some "fresh" ideas but nothing so revolutionary that they produce more than a few sparks here and there.
I believe that an entire MMO community is desperate to play that game that gave off "MMO high" the first time we played one. Take Bless Online for example. I have no idea why it got the attention it deserved for being a recycled content that has already failed twice. On release it all but failed and player base was reduced to mere thousands in a matter of weeks. People wanted something new, but once again was disappointed.
On the upside in my opinion FF14 devs are far better than let's say Bethesda. From what I've seen they are far more transparent and attentive to the community. Also I've heard rumors that they are developing new MMO, and if true I'm definitely signing on to it because I know that they will make something good, and I will be there from the very beginning.
